What would you do? (65 dart headers)

I went with the Hedman Hussler fenderwell hedders on my 410 in my 66 Dart.Ihave Eddy RPM,s P&P on my engine and had the Dougs(1 5/8)but sent them back as they would,ve restricted full potential of the engine.TTI now makes 1 3/4 hedders for Early-A,but not sure about fitting with p.steering.If you change to manual steering,it gives you more options for hedders.Theirs a post here about deals on the Dougs hedders.Here,s a pic of my fenderwell hedders.
